Improvement in water-wheels



N.PETEHS, PHOTO-LITHURAPHER, WASHINGTON, D CA dinard tant Leners Patmtlvo. 92,862, cated July 20,1869. 'I i IMPROVEMENT IN WATERWHELS.

The Schedule referred to in these Letters Patent and making part ci the same.

To all wh-om it may concern Beit known that I, FEiBrNAND MEHRMAKN, of Fountain City, in the county of Buiialo, and State of Wisconsin, have invented Aa new and useful Improvement in NVater-Wheels; l and I do hereby declare that the following is a flilhclear, and exact description thereof, which'will-enable others vskilled in the art to make and use the same, reference being had to tbe accompanying dra wings,`ibrming part of this specification, in whichv Figure 1 represents a side view, partly in section, of my improved water-wheel. Figure 2 is a plan-or top View, partly in section, of the same. Y Figure 3 is a detail perspective View of one of the buckets.

Figure 4 isa detail side view of one ofthe buckets. Similar letters ot' reference `indicate like parts.

Lhis invention relates to an improved water-wheel, which is so constructed that the .power of the water will be enti-rely exhausted, and that thewhole apparatus will be very effective, and operate most satislactolily.

llhe invention consists lin the peculiar construction of the hub and buckets, yais-will be hereinafter more fully described.

c A, in the drawings, represents the shaft or spindle of the wheel.

` 1t rests on 'a suitable step, a, and is, on top, guided in a suitable box or bushing, attached to a stationary frame.

rlhe shaft is surrounded by a spool-shaped block, B, l which forms the core ofthe wheel, and which `is large on top and bottom, and narrow in the middle, as 'indicated by section in tig. 1.

By means of bars or rods b b, the rim C of the wheel is suspended from, and held on the core B.

The inner side of the rim is convex, to correspond about with the concave edge ot' the core, as shown in iig. 1, so that au annular lspace is left between the core and rim, representing a ring, with convex inner and concave outer edge.

Wi'lliiu this space are arranged the'wheelbuckets.

Th1 se buckets l) Dare shaped as in tig'. 3, to conduct the water trom the upper to the lowerpart of the space in the wheel.

Each bucket is 'at its upper outer edge, heut outward, as at e, about in line with the partition'cl ofthe chute F, lig. 2, so that the direction of the water may not be suddenly interruptedwhen it enters the wheel.l Then the bucket makes a turn of about ninety de' grecs at f, and receives the waterl against its body g.

The body g of they bucket then gradually slopes downwardin the wheel-space, but not only downward,

and bottom plates of the chute, a gate, h, which 'can be swung open to let the water'iuto the wheel, or closed to keep it out. When the gate is swung open, as in fig. 2, it will form two water-passages, i and j, between every two partitions d, the size of the passages being regulated by the position of the gate.- When the gate is closed, as by red lines in Iig. 2, the two passages Twill be closed.

The gates canbe operated by'means of an oscillating ring, K, arranged around the shaft A, and connected, by means of rods l l, with pins m, projecting through slots in the top plate of the chute from the gates.

The ring K has a-toothed segment n projecting from it. and meshing into a pinion, O, which can be turned by a suitable handle, p.

Having thus described my invention,

I claim `as new, and desire to 'secure by' Letters Batent- The core oi' the wheel, formed by the spoolshaped block B, and the riln O, supported from the vupper iange of the block, the annular space between the block and rirn being provided with the buckets D, of the form shown in iig. 3, all operating as described, for-the purpose speciiied.
